Abstract: A header capable of fluidly connecting a plurality of spaced terminals (e.g. wellheads} to a centralized location in a frigid environment while eliminating or substantially alleviating freezing within the header. The flowpath through the header is such that it forces a relatively warm fluid (e.g. production or injection fluid) to flow through the entire length of the header before the fluid is produced or injected from the header. This allows the relatively warm fluid to continuously transfer heat to the header as it flows therethrough to provide the heat necessary to prevent freezing within the header.
